Table 2. Parameters of the beamline mirrors.

M1/M2 is the hard X-ray KB mirror pair, M3/M4 the soft X-ray mirror pair for the first endstation, and M5/M6 the mirror pair for the second endstation. Object distances are measured from the undulator source (M1, M2, M3 and M5) and the exit slit of the PGM (M4 and M6), respectively. For M1 and M2, image distances for both endstations are given.
